Abstract (en)
[origin: EP0433957A2] The invention relates to the use of aqueous vinyl ester graft copolymer dispersions with added acidic, water-soluble metal salts or free acids, as adhesives, specifically for bonding wood, having excellent resistance to hot water and a long shelf life. The vinyl ester graft copolymer is composed of 2-12 % by weight, based on the total weight of the graft copolymer, of one or more polyvinyl alcohols having a degree of hydrolysis of from 60 to 99 mol % as the graft base, and 88-98 % by weight, based on the total weight of the graft copolymer, of a graft monomer mixture. The graft monomer mixture contains 5-50 % by weight, based on the total weight of the monomer mixture, of vinyl esters of saturated, highly branched, aliphatic monocarboxylic acids having 9 or 10 carbon atoms, vinyl pivalate, diisopropyl maleate, diisopropyl fumarate, vinyl chloride or mixtures thereof.
